A CAR-10 buffer will allow you to use any AR-15 carbine (collapsible) stock (Magpul/LMT/VLTOR/etc) on your Aero Precision, AR10, SR25, LMT, LWRC, POF or DPMS-pattern .308 AR. This is strictly a 'Drop-In' part, no gunsmithing or modifications are required.

CAR-10 buffers are shorter and heavier than standard carbine buffers. Constructed of 303 Stainless Steel with a reciprocating Tungsten anti-bounce counterweight.

Heavy Buffers reduce felt recoil for the shooter, and minimize wear and tear on the gun. Many customers have reported that installing a CAR-10 buffer significantly increased the reliability of their weapon.

This product is specifically recommended by Magpul for use with their carbine stocks on .308 ARs.  CAR-10 buffers also work great with any other stock using a standard 7" carbine buffer tube.

I recommend using my custom .308 Carbine Buffer Springs with these buffers. These springs are manufactured specifically for use with CAR-10/CAR-10 XH  buffers. OEM springs and aftermarket springs (including Sprinco White/Red/Orange/Yellow/Green/Blue/Indigo/Violet/Black) may cause malfunctions. 'Flat-Wire' springs are not recommended for any application.

Note: Not compatible with AR-15s!
This buffer is only for use in .308 ARs with a standard 7" deep AR-15 carbine receiver extension (buffer tube).

DO NOT USE A CAR-10 buffer in any gun with an A5 buffer tube! Damage/injury/mayhem will result.
If you have an ArmaLite/VLTOR A5 extended length tube (7-5/8"deep) or a Magpul UBR Gen2 stock I recommend an XH Carbine Buffer.  


Also available for suppressed weapons:

CAR-10 XH (Extra Heavy) Buffer

I strongly recommend this buffer if any of the following conditions apply:

  • If you will be shooting with a suppressor. (Your gun will still run fine unsuppressed with standard ammunition.)
  • If you will be shooting hot handloads or very heavy bullets.
  • If you want maximum recoil reduction.

DO NOT USE A CAR-10 XH buffer in any gun with an A5 buffer tube! Damage/injury/mayhem will result.
If you have an ArmaLite/VLTOR A5 extended length tube (7-5/8"deep) or a Magpul UBR Gen2 stock I recommend an XH Carbine Buffer.
